SubFunctionNotSupported-InvalidFormat
This response code shall be sent if:
•
Message length of the request is invalid (less than two bytes).
•
Requested sub-function parameter is invalid (not defined or not supported).
•
$sub-function parameter = [$01 to $04] and Message length < 3.
•
The number of DPIDs in a sub-function parameter $01 request exceeds the
maximum number of DPIDs supported for one-shot.
•
The number of DPIDs in a sub-function parameter $00, $02, $03 or $04 request
exceed the maximum number of DPIDs that can be scheduled simultaneously in
the PDS. Refer to pseudo code.

RequestOutOfRange
This response code shall be sent if:
Any DPID in the request is invalid (reserved or not defined). This check is not required
for sub-function parameter $00. Checks for valid DPIDs are performed after the
checks for message format and sub-function level.
